They may be prepared by heating the diaryl ester of the corresponding amino-dicarboxylic acid at 100-200 DEG  C., where the alkyl group may contain up to 5 carbon atoms.  Esters specified are diphenyl 3-aminophthalate, diphenyl 4-aminophthalate, the diphenyl ester of 3-aminonaphthalene - 1,8 - dicarboxylic acid, 2-aminonaphthalene - 1,8 - dicarboxylic acid, 4-aminonaphthalene -1,8 - dicarboxylic acid and 5 - aminonaphthalene - 2,3 - dicarboxylic acid, di - p - tolyl 3 - aminophthalate, phenyl naphthyl 4 - aminophthalate, and the phenyl p-tolyl ester of 4-aminonaphthalene-1,2-dicarboxylic acid.

Abstract: 1325199 Phosphorus-containing metal complexes; hydroformylation of olefines PROGIL 12 Aug 1970 [12 Aug 1969] 38875/70 Headings C2C and C2P The invention comprises the complexes of Formulµ I and II and a process for the hydroformylation of an olefine to give an aldehyde which consists of reacting the olefine, in the liquid phase, with hydrogen and carbon monoxide in the presence of at least one catalytic complex of Formula III where M is rhodium, palladium, iridium or platinum, x+y= 1 if M is rhodium or iridium, and x and y = 0 for the other metals, z = 0, 1 or 2 and t=0, 1, 2, 3 or 4, such that x+y+z+t=4, and L is a trivalent phosphorus derivative, the three valencies of which are attached to up to 3 aliphatic or aromatic radicals, either via oxygen or nitrogen atoms, which atoms may optionally form part of a ring, or, if y=1 and z=0, directly, with the proviso (i) that if M is palladium or platinum, z=0 and (ii) that if M is iridium, x=1, z=1 and t=2, under an effective pressure between 5 and 50 atmospheres. The hydroformylation reaction is preferably carried out in the presence of an inert organic solvent and at a temperature of 50‹ to 150‹ C. The complexes of Formula III in which M is rhodium, x is 1, z is 1 and t is 2, or in which M is rhodium, x is 1 and t is 3, including the novel complex of Formula I, may be prepared by reacting dichloro - tetracarbonyl - di - rhodium with the appropriate co-ordinating compound. The complexes containing a hydrogen atom may be prepared by substituting hydrogen for chlorine in a corresponding chlorine complex or by exchange of co-ordinating compounds with another hydride complex. Complexes consisting solely of a central metal atom and 4 phosphoruscontaining ligands, including the novel complex of Formula II, may be prepared by reacting the ligand with a metallocene or with a zero-valent complex of the metal and triphenylphosphine.

Abstract: 887,064. Ultrasonic inspection devices. GLASS DEVELOPMENTS Ltd., and SPROULE, D. O. March 16, 1959 [Dec. 16, 1957], No. 39051/57. Class 40(7). [Also in Group XL(b)] Relates to pulse-echo ultrasonic flaw detection in which exploration by a moving probe of a test piece produces an intensitymodulated cathode-ray tube (C.R.T.) display 1, Fig. 1, representing a vertical cross-section. In the first embodiment the display is copied on to moving electro-chemical recording paper 9: slit 2 moves vertically over successive overlapping strips of the C.R.T. screen either mechanically as shown, or rotating polygonal mirrors are used. The slit scans horizontally at the speed of the exploring probe with rapid flyback by virtue of frame 6, 7 reciprocation and the amplified output of an associated photo-cell energizes stylus 8 which moves only vertically. If a display with a long delay time is used the scanning may be independent of the ultrasonic transducer movement. In the second embodiment the slit covers the whole height of the display and an associated photocell output energizes an indicator or alarm when the light flux (1) increases from that due to boundary echoes or (2) increases and subsequently decreases, so as to give an alarm only if there is a flaw above a predetermined size, Figs. 2, 3 (neither shown); in a modification slits 31, 32 are used and their associated photo-cells connected to an anticoincidence circuit which energizes an indicator or alarm relay when their outputs differ, Fig. 5 (not shown), the alarm associated with an abrupt change of test piece thickness serving to check that the apparatus is working correctly. Specifications 696,920 and 815,071 are referred to.

Abstract: 880,073. Selective punching machines. BUD M. Nov. 20, 1959 [Dec. 4, 1958], No. 39129/58. Class 31 (2). [Also in Group XIX] Punching mechanism in a workmen's time recorder (see Group XIX) is operated by a lever 18, Fig. 3, which, by turning cams 111, Fig. 2, through 90 degrees, pushes a movable support 37 away from a fixed support 36 against the action of springs 38. The springs 38 in turn urge the block 112 and guides 4 towards timeset wheels 6 against the action of springs 113. The wheels 6 carry punch-actuating projections 45 arranged according to a binary code and manually-set segments 13 carry punch-actuating projections 39 also arranged according to a binary code. All punches 41 that are in register with projections 39 are struck and displaced against springs 42 to enter dies 43 and all punches 7 that are struck by projections 45 enter dies 54. If there is a card in the pathway 3, it will be punched from opposite sides to record in binary code the time and the set number. On release of the lever 18, the parts are spring returned. The set of five punchactuating wheels 6 can be shifted bodily to register with either of two sets of punches 7 in order to distinguish, for example, a time of arrival from a time of departure.

Filed: 1975-09-29
Abstract: 1525756 Alpha-numeric character generators TEXAS INSTRUMENTS Ltd 29 Sept 1975 39747/75 Heading H4T A character generation system for a raster scanning display (of e.g. a c.r.t.) comprises a first data store 4 arranged to recirculate digital codes and addresses of data to be displayed, a second store 1 storing character data in digital form for reading out binary words to the display means under control of an address selector 2 which decodes the address codes supplied by the recirculatory store 1, and of a character line number generator 3, responsive to line code data, for calling up sequences of binary words line-by-line from the store 1, the system also including means for selectively delaying binary words by time intervals dependent upon line count in order to tilt the stems of selected characters (e.g. to reproduce italic characters). The (broadcast) data in the store 4 may have a recirculatory time equal to the field period of the raster and is loaded with a page of display data in the form of a seven-digit code which includes digits representing location of seven-digit words on the page. Each displayed character covers e.g. sixteen television lines and the store 4 is timed so that first row character data is available as the first line is scanned. The word codes for a given row are located in the store 1 and read out line by line over the odd lines (1 to 15) in the row. On completion of the whole raster, the even lines of the rows are read out. The character K is shown in Fig. 2 in a form which may be represented by seven seven-digit words, where each row requires seven lines. The words in a given line are read out of the store 1 in parallel and converted to serial form in known manner. The line-by-line read-out is controlled by a character line number generator 3 which is supplied with line address data from the store 4. The generator 3 also controls the delay circuit of Fig. 8 consisting of serial groups of logic elements which can be selectively short-circuited by NAND gates 60, 70, 80, 90. A unit of delay is provided by delay elements 61, 62, 63, two units are provided by elements 61-63 and 71-74, four units by elements 61-63, 71-74 and 81-86, and eight units by elements 61-63, 71-74, 81-86 and 91-100. By controlling NAND gates 60-90 to provide maximum delay during the first line of a row and progressively decreasing delay for the subsequent lines of the row, the stem of the characters in the row (or selected characters) may be tilted as shown in Fig. 3. The appearance of the characters may be improved by elongating the dots to form short lines.
